Buy a DeLorean on the condition of its frame, not its stainless panels. The steel frame is epoxy coated, and cracked coating can hide corrosion, so a specialist inspection from underneath matters more than a polished body.
For this November 5, 2026 guide, I checked the Silodrome DMC-12 guide, the Petrolicious buying guide and a DeLorean specialist post on frame rust. So, the checks below come from those sources, with U.S. title steps added.
Inspect the frame and epoxy coating
Silodrome explains the backbone chassis was dipped in epoxy, which protects for years but can crack, letting water start rust from the inside. The specialist post calls frame rust possibly the number one value-killer today. Ask the inspector to check the front frame extension, shock towers and rear engine cradle.
Look for grounding damage
Grounding can crack the coating whether or not the car has been lowered, though lower cars are more likely to have it. Petrolicious says the frame ahead of the front wheels is where the metal is thinnest. Note scrapes, dents and fresh coating patches, and ask how they happened.
Check under the brake servo
Petrolicious advises inspecting below the brake servo because leaking brake fluid strips the frame epoxy. The specialist post shows the same problem with leaking brake and clutch hydraulics. A wet, stained area here deserves a closer look before you accept the car.
Examine the fiberglass underbody
Silodrome notes the fiberglass body does not rust but can deteriorate, including osmosis where moisture is trapped in the layers. Look for cracks around the radiator corners and wheel wells. Ask for repair records if patches are visible.
Start the PRV V6 cold
Every DMC-12 used a normally aspirated 2.8-litre PRV V6. Petrolicious says a well-maintained engine lasts, but many now suffer from perished seals, and cars used sparingly can run poorly due to sediment in the Bosch injection metering unit or injectors. Watch the idle and ask what fuel-system work was done.
Inspect the stainless panels for pitting
Petrolicious notes stainless panels can corrode if left exposed for long periods. Look along the panel surfaces in good light. Dents in brushed stainless are hard to hide, so ask about any visible repair.
Book the DeLorean inspection with a shop that has seen the model before, and ask for a written report with photographs from underneath. Agree in advance who pays for the visit and what happens to your deposit if the findings are serious.
Use the history report for the right questions
Read title brands, dated odometer entries and changes of registration state before looking at service entries. Compare those events with the seller file and ask about gaps; a DMC-12 that sat for decades can show long silences that are normal, while a sudden mileage drop is not. The federal NMVTIS program explains its title, salvage and junk data role; it does not replace a workshop inspection. Our odometer discrepancy guide helps you separate a recorded conflict from proof of a particular fault.
Keep ownership paperwork separate from condition
Match the seller name to the title and request a written lien release where needed. Our lien-release checks explains the paperwork sequence. Federal odometer disclosure rules are summarized at Cornell LII, though older vehicles can be exempt from some disclosure requirements, so the absence of a mileage statement is not proof of anything by itself. Our service-record explainer covers what a missing service entry can and cannot tell you.
Set the offer after the inspection
Ask for separate estimates for safety work, overdue servicing and cosmetic improvements. A hypothetical $1,500 repair reserve is only a planning example; it can be inadequate on an older collector vehicle. A seller PDF can be edited, so obtain your own report using the identifier stamped on the vehicle. A frame replacement quote should be in hand before you agree a price on any car with visible rust.
